The Irony of it is, that if the
"Labour Theory of Value" applied exactly throughout, then, and only
then, would the "marginal product of capital" theory work!It would require that all products had the same
organic composition; and that ateachvalue of r each commodity had an
"alternative method", and that the relations within each pair should
be the same (i.e. that marginal products should be the same; +also the
elasticities should be the same); so that, even when the System is switched,
and another Org. Comp. came into being, it should be the same for all products.Obviously this would be equivalent to having only one
means-product (wheat).Then, commodities wouldalways be exchanged a their Values;
and their relative Values would not change, even when productivity of labor
(sic) increased.
